I remember when it first came out, the rumor was it could cause someone to lose control of their bowels involuntarily. That was the main thing that kept me from trying the chips. Now I do so because I generally avoid any diet food.
Reminds me of the SNL skit where they did a fake commercial and repeated the words "anal leakage" about 50 times during the pitch.
Not sure I would call it a "rumor" though. This was the stated impact. More likely it was something akin to a "wet fart."
Oh man, this was a gross post. Sorry. Admin should remove it.
